If you were enrolled in Medicaid when you gave birth, your baby is already covered from the day of delivery, but you still have to tell MDHHS within ten days. That ten-day notice is the single most important step in how to add a newborn to Michigan Medicaid. Most of the paperwork happens automatically between the hospital, the state birth registry, and MDHHS, and your job is to make sure nothing slips through the cracks.1State of Michigan.

Report the Birth to MDHHS Within Ten Days
Michigan requires the mother to notify her local MDHHS office of the birth within ten days.1State of Michigan. Newborn Coverage Tips Don’t wait for the birth certificate or Social Security card. The state specifically tells parents to make contact first and follow up with those documents when they arrive.2State of Michigan Department of Insurance and Financial Services. Health Insurance Enrollment for Newborns
You can report the birth four ways:
- Online through MI Bridges at newmibridges.michigan.gov. Log in, report a change to your household, add the newborn, and upload documents. This is usually the fastest option.
- By phone through the Beneficiary Help Line at 1-800-642-3195.3State of Michigan. Beneficiary Support
- In person at your local MDHHS county office. Locations are listed at michigan.gov/mdhhs/inside-mdhhs/county-offices.4State of Michigan. County Offices
- By mail using Form MDHHS-1171, the Assistance Application, delivered or mailed to your county office.5State of Michigan. Assistance Application (MDHHS-1171)
Have your Medicaid ID number ready, along with the baby’s full name, date of birth, and the hospital where the baby was born. That’s enough to open the process even without a birth certificate in hand. Send the birth certificate and Social Security card to MDHHS through MI Bridges or your local office when they show up in the mail.
Missing the ten-day window doesn’t disqualify your baby. MDHHS can add coverage retroactively to the date of birth. But reporting on time heads off billing confusion and speeds up the assignment of your baby’s Medicaid ID.
How the Automatic Enrollment Actually Works
Once the hospital reports the birth to Michigan’s Vital Records office, MDHHS runs an automated match between the newborn and the mother’s Medicaid file. When it hits, the system generates a Beneficiary ID for the baby, adds a Medicaid benefit plan, and enrolls the child in the mother’s health plan.1State of Michigan. Newborn Coverage Tips
The whole match usually takes 30 to 45 days. A slow report from the hospital pushes it out further. Babies who don’t match automatically get flagged for manual processing by MDHHS’s Enrollment Services Section, and coverage can still be applied back to the date of birth.1State of Michigan. Newborn Coverage Tips
Coverage for the baby lasts through the end of the month the child turns one, with no separate income or asset review during that first year. While you’re at the hospital, staff will ask if you want to request a Social Security number for the baby through Enumeration at Birth. It’s voluntary and it’s not required before Medicaid coverage starts, but saying yes saves a trip to the Social Security office later.6Social Security Administration. State Processing Guidelines for Enumeration at Birth
The mihealth Card and Your Baby’s Health Plan
After enrollment finishes, your baby is mailed their own mihealth card. It’s a permanent plastic card printed with the child’s name and an eight-digit Medicaid ID. Every person on Medicaid gets a separate card. The baby is still covered before the card shows up; providers can verify enrollment through the state’s provider portal or by calling MDHHS. To replace a lost card, call 1-800-642-3195 or use the myHealthPortal online.7State of Michigan. The mihealth Card
If you were in a Medicaid Health Plan when you delivered, your newborn is added to that same plan automatically, so you keep the same network of doctors.1State of Michigan.

If You Weren’t on Medicaid When the Baby Was Born
Automatic newborn coverage only applies when the mother was already enrolled in Medicaid at delivery. If you were uninsured or on private insurance, your baby is not auto-enrolled, but the baby may still qualify. Michigan’s Healthy Kids program covers children under 19 in low-income families with no monthly premium.8State of Michigan. Health Care Programs for Children
You apply the same way you’d report a birth: through MI Bridges, by phone, in person at your county MDHHS office, or by mail with Form MDHHS-1171. The difference is that the state has to verify your household income, so pull together pay stubs or other income proof before you start. The Michigan Healthcare Helpline at 855-789-5610 can help you figure out which program fits.2State of Michigan Department of Insurance and Financial Services. Health Insurance Enrollment for Newborns
If Your Baby’s Coverage Is Denied
Denials for newborns of Medicaid-enrolled mothers are unusual and usually trace back to a data mismatch, like a name difference between the mother’s Medicaid file and the hospital’s birth record. Read the denial notice; it explains the reason and how to request a state fair hearing.
You have 90 days from the date the denial notice was mailed to request a hearing. If the denial came from your Medicaid Health Plan and you’ve already finished the plan’s internal appeal, you have 120 days from the date of that notice.9State of Michigan.
